O NH, only O NH, and NH, O NH," and H" O I' only O NH, only Question 25 What is the pH at point B? 9.26 4.74 O 7.00 O A pH other than what's listed O 11.13 Question 2o What major species is (are) present at point B? OH only O NH, only O NH3 and NH. O NH3 only O NH, and OH" Which of the following represents the approximate pH at the equivalence point of the titration? O pH = 7 O Impossible to determine O pH < 7 O pH > 7
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
